Techniques for Tracking, Evaluating, and Reporting the Implementation of Nonpoint Source Control Measures - Urban

Techniques For Tracking, Evaluating, And Reporting The Implementation Of Nonpoint Source Control Measures - Urban (PDF) (105 pp, 951K, About PDF)

The initial purpose of the urban tracking guidance was to help Coastal States and local governments assess the implementation of management measures required to meet requirements of the Coastal Zone Act Reauthorization Amendments of 1990 — specifically the urban management measures and practices found in Chapter 4 of the "Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters", EPA 840-B-92-002, January, 1993. Statistical analyses can substantially reduce the cost to determine the extent of BMP implementation and effectiveness of operation and maintenance activities. A statistically-based, accurate inventory of implemented BMPs and data on their effectiveness is necessary for any effort to correlate BMP implementation with changes in water quality. Although BMP effectiveness monitoring is not addressed, it is a logical follow-up to implementation monitoring.
